PHILIPE´S DIARY

On some days it´s raining less. And on some days it rains only once. This happened during my visit to Denmark, where it rained only once in 6 days: from my departure from Sweden on Monday, September 4th without stop until Friday, September 8th.

The variations of rain were very subtle. From drizzle to rainfall and thunderstorms, every form of rain occurred. There was enough time to intensively consider all these forms of rain – it took me 6.5h to drive from Copenhagen to Hamburg. Not a single minute without a break of rain in between.

The only good things were the 45min I spent inside a ferry that took me from Rødby (Denmark) to Puttgarden (Germany). This 45min dry minutes I dedicated myself to the all-you-can-eat buffet, which was priced as twenty-one Euros. 21 €, which I (famished, as I was) extremely gladly paid. (And the unlimited-free refill of the hot coffee was then the decisive criteria for the almost instantaneously made decision).

HYBRID FERRY

A few days ago, I read an interview by Bertrand Reydellet, a colleague of the Transport Research Arena.
Digitization has also not stopped in the shipping industry. The Tesla principle is also found here: We were passing another ship, which captivated my attention. The word “Hybrid Ferry” was visible on the side.

After my arrival, I researched a bit on this topic.

The Scandlines shipping company uses diesel ships on the approximately 50 km route from Rødby to Puttgarden, which are powered by an electric motor.

How it works? Four diesel generators generate electricity, which is temporarily stored in accumulators and is then used by electric motors to move the 8800 tons of the ship.

The great advantage of this solution is that the diesel generators are operated only in their ideal working range of approx. 85 to 90 percent of their maximum load.

Of course such a “green” ferry also has an extended exhaust gas clarification and filter system. (If you want to know more about this topic, you will find it here.)

By the way – in order to illustrate the numbers: On the route from Rødby to Puttgarden and Rostock to Gedser in the year 2015 7.5 million persons, 1.8 million cars and innumerable goods were transported.

That means that every year, more than all Austrian citizens were moved together. Therefore each percentage point of energy saving makes a lot of sense.

All this is written – fortunately I am now in Hamburg with friends.

… which have welcomed me very kindly to cure my violent cooling, which I have opened up by this rainy ride and which is currently curling me.
